First Generation [1G]

In the wireless context, first generation (1G) is used to identify the first generation of mobile air-interface technologies, which were analog rather than digital.

The first generation of cellular technology in the United States was the Advanced Mobile Phone System (AMPS), an analog standard deployed in the 1980’s until the FCC stopped requiring it in 2008. AMPS provided analog voice and data rates up to 9.6 Kbps.
